none (well if you slant the mirror, then it would be two) why - because that's the parallelogram's theory :)
parallelogram
No
If you draw a diagonal line from corner to corner of a parallelogram, that is a line of symmetry.

A parallelogram has no lines of symmetry, but it has rotational symmetry.
There are 0 lines of symmetry in a parallelogram.
a parallelogram has 2 lines of symmetry
A parallelogram need have no lines of symmetry.
They have NO lines of symmetry

Usually none.
None
Squares, which are parallelograms, have four lines of symmetry. Rectangles have only two. Rhombi have two lines of symmetry. Generic parallelograms don't have any lines of symmetry.None normally unless it is in the shape of a rectangle in which case it will have 2 lines of symmetry
Normally none unless it in the shape of a rectangle which has 2 lines of symmetry
